Magnitude A varies proportionally with (B squared + 4) and magnitude B varies proportionally with
(the root of C) β 5. Also when A is 16 , B is 12 and C takes the value 81. Calculate the value that A takes
when C is 49. help me. please. thanks
The real roots of the equation x^2 +6x+c=0
differ by 2n, where n is a real nonβzero.
Show that n^2 =9βc
Given that the roots also have opposite
signs, find the set of possible values of n
